There are two very different Koreas in the real world. http://i.imgur.com/v9FyEtL.jpg PAC also has the least amount of korean city names. (2 korean cities vs. 3+ for other languages). They could also slip Taiwan into the pacific naval faction as well. Either Taiwan gets swallowed up by China after the Great Mistake, or they form a united front with Japan/South Korea to keep their autonomy.
